heating controls

[rocketman]

Hi all,

just after some recomendations for heating control system (pack) for my own gaf. Nearly finished almost complete new system, all new rads bar a couple have been replaced. Cleaner in system already before system drain down on Monday.

System was gravity primaries (28) and pumped heating (28f 22 r). Problems are (nearly were) all the ground floor heating is in concrete floor.
(had 1 leak about 4 years ago and was a nightmare to cut in to the floor to find the leak....never again*) Discovered non of the copper in floor appeared to be protected:-(. Almost finished routing it all upstairs. New boiler in today (WB standard 30cdi). Old system to be decomissioned Monday. Just after recomendations for a control pack. A must is a wireless room stat. Don't mind spending a bit more on own place...

any recomendations ???

*very prevelent around here. Regularly get calls for pipes leaking in floors (due to unprotected copper), just cannot understand how they got away with it circa 30years ago..was there no building control?????

By standard do you mean it is not a combi, i.e you have a hot water cylinder?

yep, heat only

OK, you will need (some of this you may have already):

Wiring centre (aka junction box)
Cylinder thermostat
Either one mid-position valve or two zone valves.
HW Programmer
CH programmers
CH thermostat.

The last two can be combined as programmable thermostats

Most wireless programmable thermostats are single channel devices only, so you need a separate single channel timer for the Hot water. This can be located near the HW cylinder and, as it is not altered very often, that should not be an inconvenience.

I would recommend the Honeywell CM927 for the CH programmable thermostat and, for HW, Honeywell ST9100A or ST9100C or Drayton Tempus 1 or Tempus 2.

There are two channel wireless controls, but these are intended for separate heating channels. There are also wireless HW controls, but they are expensive and not very practical
